Abstract
In this paper, methyl vinyl silicone rubber was prepared by high-energy electron beam irradiation. The effects of irradiation dose on the properties and structure of silicone rubber were studied, and the performance differences of vulcanizing agent content under different irradiation doses were analyzed. The experimental results show that electron beam irradiation can promote the crosslinking of methyl vinyl silicone rubber. With the increase of absorbed dose, the tensile strength, shore hardness and crosslinking density of silicone rubber increase, and the breaking elongation first increases and then decreases. At the same time, the content of vulcanizing agent has no significant effect on the degree of irradiation crosslinking and shore hardness, but the silicone rubber without vulcanizing agent has excellent tensile strength, elongation at break and tear strength at the dose of 60-100kgy. Relevant data show that irradiation crosslinked silicone rubber material can improve the performance of silicone rubber, and the performance is significantly improved without vulcanizing agent in the electron beam irradiation system, which can provide guidance for the preparation and processing of silicone rubber.
